This meta-analysis examined main effects and heterogeneity in associations between popularity and academic adjustment in the U.S. and China across 41 studies. The aggregated sample included 22,151 children and adolescents (10,934 boys; 11,217 girls) from both countries, with U.S. students from various ethnic backgrounds. Results in the U.S. were…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

When making moral judgments of past actions, adults often think counterfactually about what could have been done differently. Considerable evidence suggests that counterfactual thinking emerges around age 6, but it remains unknown how this development influences children's moral judgments. Across two studies, Australian children aged 4-9 (N = 236,…

With development knowledge becomes organized according to semantic links, including early-developing associative (e.g., juicy-apple) and gradually developing taxonomic links (e.g., apple-pear). Word co-occurrence regularities may foster these links: Associative links may form from direct co-occurrence (e.g., juicy-apple), and taxonomic links from…

Overparenting--taking over and completing developmentally appropriate tasks for children--is pervasive and hurts children's motivation. Can overparenting in early childhood be reduced by simply framing tasks as learning opportunities? In Study 1 (N = 77; 62% female; 74% White; collected 4/2022), US parents of 4-to-5-year-olds reported taking over…

Dimensional comparisons (i.e., comparing own performances across domains) may drive an increasing differentiation in students' math and verbal self-concepts over time, but little longitudinal research has directly tested this assumption. Using cross-sequential data spanning Grades 1-12 (N = 1069, ages 6-18, 92% White, 2% Black, 51% female,…

Social skills are dynamic developmental constructs typically measured using assessments developed via cross-sectional methods. The measurement model of derivatives (MMOD), a factor analytic approach targeting individual growth trajectories, was used to evaluate the longitudinal factor structure of the Social Skills Improvement System--Rating…
